The Untold Secret Behind Fuel Pump Priming Problems.

[@barryc1635]

I’m glad this worked for you. I’m the guy that made the original video about the IC17 issue. It was a lucky find on my part and a big issue for many people.

[@SIRICKO]

I see this is A bigger problem then I thought.

[@cede3946]

Have a 1997 Honda civicHX (different lol ) got it for 300 crank no start with 264k miles little old lady just got to old To drive it and sold it to me ! same issues went to junkyard after replacing the fuel pump tune up oil change so I started googling no prime from the fuel pump instead of just crank no start and I came across 3 videos pointing the ecu! Got it two weeks ago and after watching your video and 3 others I ended up a junkyard got one from a sedan 1.6 5 speed! I said If I plug it up then it primes we got ourselves a car ! THAT THING PRIMED UP AND STARTED ! Thanks so much and it’s exempt antique tag here I come lol

[@hectorgonzalez7806]

I just want to say if it wasn’t for you, I wouldn’t fix my Honda fuel problem. I tried so many stuff and it was the computer. Thank you and keep doing a good job.

I’ve been trying to figure out the issue on my Honda del sol for months now and I’m so glad I found this, I hope to god that it’s the issue and that I fix it, I’ll update later on this week when I get a new ecu or heat the og ecu

So glad I was able to help my boy.

[@pedromachado623]

THANK YOU SO MUCH !! You saved me a lot of money! It is the IC17 TA8903SN emulator i heated it up a bit with a heat gun and the fuel pump had absolutely no delay at all! I will now switch that out but I will find someone with experience to do that for me. THANK YOU AGAIN YOUR THE MAN!

[@SIRICKO]

Thanks my man glad i could help you out. It seams A lot of people have had this problem and no one knew.

[@peterle_garage]

Where you buy this emulator TA8903SN?

[@fivefivesix-sevensixtwo4114]

I think I have this same problem. I have a 92 Integra that has starting issues out of nowhere. I don't hear the pump prime and car just cranks. I replaced the fuel pump with a Denso pump, drove it for a lil bit with no problems. The issue came back and I wasn't sure why. I replaced the main relay since I always carry a spare. Then I verified the relay was good by checking all the signals and hearing the clicks. I verified the pump is good by powering it directly. I checked continuity from relay to pump, relay to ECU. When I removed the ECU the area was wet, fixed my water leak and figured the ECU might've gotten shorted. Oredered another ECU from Ebay but the issue was still there. Found a corroded ECU ground at the thermostat housing, cleaned terminal, replaced bolt, verified continuity to ground is good. The issue is still there. It's an intermittent problem. When I checked the signals at the relay, I wasn't getting an ECU signal at times. This is probably my issue! It makes sense because I would drive it to work and turn it off and on as soon as I would get there to make sure it starts (car/ECU was still warm). Once it was time to go home, it wouldn't start (after the car/ECU cooled down). I'm going to order that chip. I'll update when I confirm if it worked or not.

Having the delayed fuel pump prime in morning, I tried to replace the 7 capacitors and i think i ruined the board, everyone made it sound like soldering was easy but it wasnt at all. The capacitors looked fine, too . Wish is saw this video earlier.

[@margar2321]

after a lot of rain driver and passenger front carpet is soaking wet water is seeping in somewhere in those areas in my 92 Civic ex and car won't start pump doesn't prime only after car completely dries out after all the towels I put to soak up the water the car will start but this time instead of waiting for car to dry out I changed out ECU and car started wish I would of picked up a few more of those ecus at the pull a apart back in the day cause they are rare now I hope I can learn how to resolder that part u talking about or the fuel pump priming capacitors cause it sounds like the same problem

[@SIRICKO]

You ay have this proble then.

[@zxryanieri]

gracias desde uruguay es como tu dises tengo ese problema y lo resolvi gracias a ti gracias

[@pirata210]

Que hiciste para repáralo

[@davidbanna394]

I just fixed this issue. I swapped from obd2 to a chipped p06 a while back and it started having the same issue. Sometimes it would take 8min with key on before it would prime. My obd2 ecu had no issues so I swapped that chip and walla primes immediately every time

[@JDMluvDSMkila]

where you buying the replacement ecu parts to solder in?

[@DavidJoyisquality]

Pumped dude! I ordered 5 of those things. I replaced and re chipped another ecu only to have the same issue. So then I put in my original p28 and it worked, only to have the same issue again. Every time it got cold lol

Thats how some perfectly 92-95 civics end up at the junk yards with new dizzys , fuel pumps etc etc that the “mechanics” think it is and make people spend thousands and then end up at the junk yards

Don't try to solder ICs with lot of pins without experience! Try to ask for professional help!

[@fuelup7504]

I had this exact same thing in my 92EG si with a GSR swap I had a grams fuel pump brand new new fucking relay and I’ll always have this issue when I was cold I would have to disconnect my fans because they ran directly just leave the key open for 15 to 20 minutes then the fuel pump with prime and I’m in ca Central valley it ain’t that cold out here lol never could figure it out I just lived with it

[@timduncan184]

Yep had the same problem with my p28 too. Wow. But I would have to put my key in the on position and let it set for 2 or 3 minutes before it would prime. Mostly in the mornings when it's cold out. I live in CA. But most of the time it would start right up. But sometimes it would fuck me. So I took out the ecu sprayed it down a good cleaning and I have never had the problem again.

[@bige989]

What you clean it with?

[@vinnyfuller6378]

what did you clean it with ?

[@a159ceo4]

Can you also link the component where to buy it from and what the chip is called

Thanks for the info. I got a p28 socketed for a s300 as well, was having the same problem. Had it in my lsv turbo ek, thought I had a short in my fuse box wiring cuz it kept blowing fuses. Took the ecu out put it in my integra and it turned over but wouldn’t start, just like my ek but it just didn’t blow fuses. Imma try this trick out sometimes and let you know it it goes.

--hi I have a Honda EG fuel pump not priming, pump, the main relay is ok I already changed the C14 capacitor, now could it be the IC C17 TA8903? I f I have to get a new ECU, the engine is D16Y1, do I also need to get the Key assembly. ( Im from Australia and the car has immobiliser)

Naw you should just be able to put the ner one in and he good. If you'er tuned you will need to swap your chip in the new ecu.

[@arcajay2157]

In my case its the opposite. Car starts every time in the cold & one random hot day the fuel pump will not prime what so ever.

[@angelogotrice]

Change main relay that’s what stops working on hot days

[@kangsojin657]

i have mini-vtec d15b, i had issues on expired unleaded fuel due to pandemic was not able to use the car for a long time, then my fuel line hoses broke down, hard starting, noisy walbro fuel pump. so i changed all the fuel hoses from my fuel rail, gas tank & fuel filter. i cleaned the throttle, drained the expired fuel changed it to premium gas, changed the air hoses. now the pump noise is gone & now engine is running okay but suddenly my check engine had a steady light when starting & had a rough idle. i tried to reset the ecu but it wont reset even i removed the ground terminal for 10mins. so i suspected the ecu might be the problem since we tried to plug my ecu to another car and still the check engine did not disappear and had the 2nd car running bad. when we placed the original ecu to the 2nd car it was okay, back to normal. so our suspect is my ecu is at fault. the next day after filling up my mini to a full tank of premium gas the check engine is gone back to normal again. but i still have my doubts on the ecu. so let me know where i can buy a reliable ecu obd1 out there..
